Golf Club Face Plate Cell Lattice for Weight and Strength Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club head technologies face challenges in enhancing playability characteristics while managing weight and mass distribution, particularly at locations of high stress and limited thickness, without compromising structural resilience.
Innovation Solution
The implementation of a golf club face plate with an internal cell lattice structure, comprising an inner skin, an outer skin, and a midsection with a cell lattice that is fully bounded between the two skins, allowing for weight redistribution and improved stress distribution through a diffusion bonding process, which encapsulates the cell lattice within the face plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If weight is reduced in the golf club head, then energy transfer to the ball is improved, but structural resilience is compromised
Solution Approach 1:
The patent introduces a cell lattice structure with controlled porosity into the golf club head, specifically in the crown and sole regions. This porous configuration reduces overall weight while maintaining structural integrity through the geometric arrangement of cells, resolving the contradiction between weight reduction and structural resilience
Solution Approach 2:
The patent combines different materials with varying properties within the club head structure. High-strength materials are used in critical load-bearing areas while lighter materials are used in non-critical regions, creating a composite structure that optimizes both weight and strength characteristics
2Adaptability or versatility
If mass is redistributed to enhance playability characteristics, then performance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the club head into distinct functional zones with different mass distributions. The cell lattice structure is segmented into specific regions (crown, sole, face) allowing independent optimization of playability characteristics in each zone while simplifying the overall manufacturing process through modular design
Solution Approach 2:
The patent applies different structural configurations to different locations within the club head. The cell lattice parameters (cell size, shape, density) are locally optimized for specific functional requirements, enabling enhanced playability characteristics without requiring complex manufacturing throughout the entire structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach results in a weight reduction of up to 25% without compromising strength or durability, allowing for better energy transfer to the golf ball and increased ball speed, while enabling additional discretionary weight to be positioned elsewhere on the club head for improved performance characteristics.
Implementation Method 1
bounding the midsection can comprise diffusion bonding the inner skin, the midsection, and the outer skin together, including the first and second midsection layers, into a single integral piece of material that is substantially seamless between the inner skin and the midsection and between the midsection and the outer skin
